"Janitorial Supplies"

Every classroom that wants to investigate spectroscopy needs a good-quality spectrum tube and power supply.

Students understand atomic line spectra in a whole new light.

This safe spectrum power supply features encased spectrum tubes.

Essential supplies to build and measure electric circuits.

Set of 9 cubes, 25 mm side. Supplied in wooden box.

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.

High quality linear expansion apparatus to study thermal expansion.

Hooke's Law apparatus, includes weights for demonstration.

Steel tuning forks for physics experiments.

Force table is inexpensive and light in weight.

Make the study of light and color fun and easy

Plastic disc to demonstrate rotational energy.

This activity illustrates the relationships of mass, potential energy, and kinetic energy with marble races.

High Quality.
